例子比较简单 记录下思路

1、接口中定义 实体和方法声明

        //登录信息

        [OperationContract]         [WebInvoke(UriTemplate = "LogInf/{name}/{pwd}", Method = "POST", ResponseFormat = WebMessageFormat.Json)]          LogInf GetLogInf(string name, string pwd);

 

   2  //数据交换实体类

  [DataContract]  

    public class LogInf     {

        [DataMember]

        public string UserId { get; set; }

        [DataMember]         public bool LogTag { get; set; }

        [DataMember]

        public string errMsg { get; set; }

    }

 

3服务实现

//简单测试

 public LogInf GetLogInf(string name, string pwd)

        {             LogInf loginf = new LogInf();             if (name == "111" && pwd == "111")             {                 

                loginf.UserId = "100";

                loginf.LogTag = true;                 loginf.errMsg = "成功";

            }

            else             {                 loginf.UserId = "0";                 loginf.LogTag = false;                 loginf.errMsg = "验证失败";             }             return loginf;         }

 

4在web.config中将绑定方式改成webHttpBinding

binding="webHttpBinding"

5 调用

      NSURL *url = [NSURL URLWithString:@];  

    ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];  

    [request setRequestMethod:@"POST"];  

   [request startSynchronous];  

    NSError *error = [request error];  

   if (!error) {  

       NSString *response = [request responseString];  

       UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"测试" 

                                                            message:response  

                                                           delegate:nil  

                                                  cancelButtonTitle:@"OK" 

                                                 otherButtonTitles:nil];   

       [alertView show];  

       [alertView release];  

    }  

 

6返回

{"LogTag":true,"UserId":"100","errMsg":"成功"}
